According to the present invention, the sequencer is arranged for, after saving the series of external words in the buffer memory, saving, in the buffer memory, internal words present in the target page and corresponding, due to their address in the page, to locations of words in the buffer memory that have not received any external words, then erasing the target page and saving in the erased page the words present in the buffer memory.
